This application claims the benefit of the filing date of U.S. Provisional Application No. 62/486,874, filed on Apr. 18, 2017. The contents of U.S. Application No. 62/486,874 are incorporated herein by reference in their entirety.

BACKGROUND

Stores often provide pricing and other product information on the shelves on which products are displayed. Sometimes stock is exhausted or must be rearranged, and pricing information needs to be occasionally updated. Sometimes additional signage is applied to shelf fronts to indicate a temporary sale. Some stores do not use shelving tags and instead use other signage or rely on the product itself as the signage. Refrigerated displays will typically have a glass door that must be opened to gain access to the product, arranged on shelving within the refrigerated space. Restocking such shelves is generally done from the rear of the shelf, by a stocking clerk. Improvements are sought in displaying and updating product information on shelves, and managing store inventories.

DETAILED DESCRIPTION

FIGS. 1A-1C illustrate an exemplary shelving display 100. Shelving display 100 includes a display housing 103 mounted at a forward end 122 of a product shelf 102. An electronic display 104 and product sensors 112 are mounted to display housing 103. Electronic display 104 is arranged to be viewed from in front of shelf 102. Electronic display 104 is controlled to present desired images along the width of shelf 102. The images can be related to products 106, 108, 110 placed behind housing 103, e.g., the images can include product pricing information and sale information. Furthermore, images displayed on electronic display 104 can be altered in response to output of the product sensors 112.

Shelving display 100 is controllable to present images that are relevant to products 106, 108, or 110 located behind various sections or widths of electronic display 104. For example, as shown in FIG. 1A, a first portion of electronic display 104 shows a price of $1.95 for product 106, a second portion of electronic display 104 shows an advertisement indicating a sale price of $4.95 for product 108, and a third portion of electronic display 104 shows an advertisement for a sale price of $5.95 for product 110. Furthermore, images presented on electronic display 104 can be altered in response to output of product sensors 112. For example, images presented on electronic display 104 can be adjusted in size to match a width of shelf 102 occupied by a product. Thus, if a product sensor output indicates that the left-most row of product 106 is empty, the size of the “$1.95” price image can be adjusted to match the width of shelf 102 occupied by the remaining three rows of product 106. For example, the size of the size of the “$1.95” price image can be automatically adjusted to match the width of shelf 102 occupied by the remaining three rows of product 106

Electronic display 104 can be a continuous display that extends along the width of shelf 102. In some implementations, electronic display 104 extends along a majority of the width of shelf 102. That is, electronic display 104 can continuously extend a distance along shelf 102 to cover a width that is sufficient to extend in front of products space for multiple different products 106,108, 110. In some implementations, electronic display 104 extends along the entire width of shelf 102.

Electronic display 104 can be a thin flexible display mounted to housing 103. As illustrated in FIG. 2C, electronic display 104 can be mounted to housing 103 by being inserted within a channel 124 of housing 103. Housing 103 can, thereby, serve as a protective covering for electronic display 104. Housing 103 can be constructed of a transparent or semi-transparent material. For example, housing 103 can be constructed of a plastic material, a polymer material, or glass. Housing 103 be configured to reduce glare on the front surface, through which electronic display 104 is viewed. For example, housing 103 can include an anti-reflective coating.

Electronic display 104 can be a digital display. For example, electronic display 104 can be a liquid crystal display (LCD), a light-emitting diode (LED) display, an organic light-emitting diode display (OLED), or an electroluminescent display (ELD). Electronic display 104 can be a static digital display, e.g., an electrophoretic display. In implementations in which shelving display 100 is installed inside a refrigerated cabinet, it may be preferable to use an electronic display that has a low thermal output (e.g., an OLED) to minimize the amount heat introduced into the refrigerated cabinet by display 104.

Products sensors 112 are arranged to detect product placed on a respective width of shelf 102. For example, referring to FIG. 1B, product sensors 112 a, 112 b, and 112 c are arranged on a back-side of housing 103 to each detect product placed on respective widths 113 a, 113 b, 113 c of shelf 102. In addition, as described in more detail below in reference to FIG. 3, each product sensor 112 can be associated with a respective width of electronic display 104. For example, output from each sensor can be used to control images displayed along a respective width of display 104. For example, as illustrated in FIGS. 1B and 1C products sensors 112 can be mounted in alignment with the respective width of display 104 which their output is used to control. As shown in FIGS. 1B and 1C, product sensors 112 are mounted directly behind a portion of display 104 for which the output of each respective sensor 112 is used to control.

Product sensors 112 can be proximity sensors or imaging sensors. For example, proximity sensors include sensors that are capable of detecting the presence of an object near the sensor with or without the object contacting the sensor. In addition, some proximity sensors can detect a distance to an object in proximity to the sensor (e.g., a ranging sensor). Proximity sensors can include ultrasound sensors, laser sensors, and optical sensors (e.g., IR sensors). Imaging sensors can obtain still or video images of an object near the sensor. Imaging sensors include low and high resolution optical or infra-red cameras.

In some implementations, product sensors 112 can be mounted at a rearward end of shelf 102. In such implementations, each product sensor 112 can still be arranged to detect product on the respective width of shelf 102. Each product sensor can be arranged to detect product on shelf 102 from a forward facing direction. That is, product sensors 112 can be directed towards a back portion of each respective row of products 106, 108, and 110 (e.g., the sensors 112 are facing the back of the last product in the row). In such implementation, product sensors 112 can be configured to detect distance. For example, a rearward mounted sensor 112 can be configured to provide an output signal that indicates a distance along the depth of shelf 102 between the location of the sensor and a respective product 106, 108, or 110 at the back of a row of products. A shelving display controller (discussed in more detail below) can use the distance measurement to detect whether the row of products is out of stock, low on stock, or both.

In some implementations, shelving display 100 can include pairs of product sensors 112 where each pair of sensors is configured to detect product placed on a respective width of shelf 102. For example, a given pair of product sensors 112 can include one sensor mounted near the forward end 122 of shelf 102, e.g., on housing 103 as shown, and a second sensor mounted near the rearward end of shelf 102, as described above.

Referring again to FIGS. 1A-1C, shelf 102 can be a flat shelf or a gravity feed shelf. For example, a flat shelf is one in which products 106, 108, 110 from the back of a row of products do not automatically move towards the front of the shelf when a product is removed from the front of a row. A gravity feed shelf allows products 106, 108, 110 to feed forward (towards the front of a shelf) when a product is removed from the front of a row. Shelf 102 can include spacers 114, e.g., to separate different products. Shelf 102 can include rollers 116, e.g., to facilitate gravity feeding of products.

FIG. 2 is a block diagram of an exemplary control system 200 for shelving display 100. Control system 200 includes a controller 202 coupled to display 104 and product sensors 112. Controller 202 controls the operations of electronic display 104 in accordance with input received from product sensors 112.

Controller 202 includes a communication interface to communicate with other computing systems over network 208. Controller 202 can communicate with computing system 204 and user computing device 206 over network 208. Computing system 204 can be, for example, a server system that stores information related to products displayed on retail shelfs in a store. User computing device 206 can be a computing device used by store personnel. For example, user computing device 206 can be, but is not limited to, a point of sale (POS) system, a desktop computer, a laptop computer, a tablet computer, a wearable computer, a handheld computer, or a smart phone.

Controller 202 can obtain product location data. Product location data can include data that indicates the planned locations of products along the width of shelf 102. That is, product location data indicates which products (e.g., by type, brand, name, sku number, etc.) are placed in in which location along the width of shelf 102. Product location data can be represented as, for example, a planogram that indicates the desired location of different products along width of shelf 102. Controller 202 can use the product location data to identify which products (e.g., by type, brand, name, SKU number, etc.) each product sensor 112 will be used to monitor. For example, controller 202 can use the product location data to correlate the positions of products along the width of shelf 102 with the respective portion of the width of shelf 102 that each sensor 112 is arranged to monitor. Controller 202 can, thereby, associate each sensor 112 with a particular product. In some implementations, the product data (e.g., a planogram) can provide a mapping between products and sensors 112. For example, a planogram can associate each sensor (e.g., by a sensor ID number) with a particular product.

Controller 202 can communicate with computing system 204 to obtain information associated with products displayed on shelf 102. Controller 202 can obtain product image data. Product image data can include data that represents product images to be presented on a portion of electronic display 104 that is positioned near a respective product. Product images can include, but are not limited to, product pricing, sales information, advertisements, product logos, coupons for products, video demonstrations of a product, suggested uses for a product (e.g., as an ingredient in a recipe), or any combination thereof.

Controller 202 receives sensor data from product sensors 112. For example, controller 202 can occasionally poll each of the product sensors 112. In response to begin polled, each sensor 112 transmits sensor data to controller 202. The sensor data can be binary data, for example, indicating whether or not product is detected within the respective portion (e.g., the respective width) of shelf 102 that is monitored by the polled sensor. The sensor data can include a distance measurement, for example, indicating a distance along the depth of shelf 102 between the polled sensor 112 and product located within the respective portion (e.g., the respective width) of shelf 102 that is monitored by the polled sensor. The sensor data can include an image of product located within the respective portion (e.g., the respective width) of shelf 102 that is monitored by the polled sensor.

Controller 202 determines whether the sensor data indicates that product is present within the portion of shelf 102 that is monitored by each sensor 112, and, in some implementations, how much product is present. For example, if the sensor data is binary sensor data, controller 202 determines whether or not the value of the sensor data indicates that product is present within the portion of shelf 102 that is monitored by the respective sensor 112. If the sensor data includes a distance measurement, controller 202 can determine how much product is present within the portion of shelf 102 that is monitored by the respective sensor 112. For example, controller 202 can use a threshold distance measurement as an indication that the stock of a given product on the shelf is low. For instance, a distance measurement that is greater than (or less than—depending on the arrangement of the sensor on shelf 102) the threshold distance can indicate a low stock condition. A different threshold distance (e.g., a distance comparable to the depth of an empty shelf) can indicate an out of stock condition.

Controller 202 can control electronic display 104 to present different images in a portion of the display that is associated with each sensor 112 based on whether or not product is detected within the portion of shelf 102 that is monitored by each sensor 112. FIG. 3 shows a series of diagrams 300A-300C illustrating control of electronic display 104. As shown in diagram 300A, controller 202 can the images presented along electronic display 104 according to virtual partitions along the width of the display. The partitions can be represented by pixel groups 104A-104N of the electronic display 104. Each pixel group 104A-104N encompasses a respective width of the electronic display. Controller 202 can associate each pixel group 104A-104N with a respective product sensor 112 or a respective group of product sensors 112. For example, as shown in diagram 300A, the width of each pixel group 104A-104N can be comparable to the respective width of shelf 102 that is monitored by each sensor 112.

Controller 202 can arrange product image data for each respective product 106, 108, and 110 to be presented in appropriate locations of electronic display 104. For example, controller 202 can identify appropriate locations along electronic display 104 based on associations between the pixel groups 104A-104N and respective product sensors 112. Controller 202 can arrange and scale product image data associated with each product 106, 108, and 110 to be presented in the appropriate pixel groups pixel groups of electronic display 104. For example, as illustrated in diagrams 300A and 300B, a product image 302 that is associated with product 106 is displayed within pixel groups 104A-104C. Furthermore, each pixel group 104A-104C can be associate with product sensors 112 a-112 c of FIG. 1B, respectively, which controller 202 can use to display product images 302 in an appropriate location along the display. Diagrams 300A and 300B also illustrate product images 303 and 304, which are associated with products 108 and 110, displayed in pixel groups 104D-104E and 104F-104G.

Controller 202 can alter the images displayed in each pixel group 104A-104N of electronic display 104 based on input received from an associated product sensor 112. For example, diagram 300C illustrates that product 110 is out of stock. In response, controller 202 can detect the out of stock condition based on data received from respective product sensors 112, and alter image 304 that is displayed in pixel groups 104F-104G accordingly. As another example, diagram 300C illustrates that one row of product 106 is out of stock. In response, controller 202 rescales product images 302 (e.g., the price of $1.95) to fit within only pixel groups 104A-104B and obtains a different image 305 to present in pixel group 104C. For instance, when controller 202 detects that product 106 located in a portion of shelf 102 that is monitored by sensor 112 c is out of stock, controller 202 can alter the images displayed in the respective pixel group of electronic display 104. More specifically, controller 202 can determine that product 106 is not completely out of stock, because other product sensors 112 that monitor portions of shelf 102 used to stock the same product 106 do not indicate an out of stock condition. Therefore, controller 202 can repurpose the portion of electronic display 104 that is in front of an empty row of product for another use such as an advertisement.

In some implementation, controller 202 can send notifications to store personnel to inform them when a product is out of stock on shelf 102 or low on stock. For example, upon detecting and out of stock condition or a low stock condition, controller 202 can send an appropriate notification to user computing device 206. The notification can be sent in a proprietary format or a general format. A proprietary format notification can include a notification that is sent only to particular user computing devices 206 associated with the store (e.g., POS devices) or to computing accounts associated with a store manager or store owner). A general format notification can include a notification sent in a general format including, but not limited to, an SMS message or an e-mail message.

In some implementations, controller 202 can control electronic display 104 to present different images in a portion of the display that is associated with each sensor 112 based on whether or not a low stock condition is detected within the portion of shelf 102 that is monitored by each sensor 112.

In some implementations, controller 202 can control the operation of multiple shelving displays 100. For example, one controller 202 can be used to control the operation of a shelving displays 100 multiple shelves of a shelving display unit.
